Abstract: An electronic device includes: a display device, a processor operatively connected to the display device, and a memory operatively connected to the processor. The memory stores one or more instructions that when executed, cause the processor to: determine, as a second screen code value, a code value obtained by reducing a first screen code value corresponding to a luminance value of a screen of the display device by a decrement based on the screen being maintained in a turned on state during a first specific time after a screen-off condition of the display device is satisfied, and change the luminance value of the screen to correspond to the determined second screen code value.

Abstract: A multi-mode bias modulator operating in envelope tracking mode or average power tracking mode and an envelope tracking power amplifier using the same are disclosed. The envelope tracking power amplifier includes a multi-mode bias modulator and a power amplifier. The multi-mode bias modulator generates a variable bias voltage using a linear amplifier and a switching amplifier operating in envelope tracking mode or average power tracking mode in accordance with an operation mode control signal that determines any one of envelope tracking mode and average power tracking mode. The power amplifier is biased in response to the variable bias voltage, power-amplifies a radio frequency (RF) signal, and outputs the amplified RF signal to an antenna.
